 of the fruit, the vines are hardy, vigorous and productive. 

 These good characters, however, cannot make up for the several 

 defects of the variety. The grapes dro]) and crack badly and 

 the pulp is tough and adheres too firmly to the seed for a des- 

 sert grape, so that the variety is worthless except for breeding 

 purposes. Hercules was introduced by G. A. Ensenberger, 

 Bloomington, Illinois, about 1890; its parentage is unknown.
